Will this bolt directly to my existing cooling system without modification?

Yes. This radiator mounts at the factory attachment points — no drilling, welding, or bracket fabrication needed. Drain and refill coolant before installation.

Do I need new hoses or can I reuse the originals?

Reuse is fine if your upper and lower hoses are in good condition. If they're cracked, brittle, or haven't been replaced in 5+ years, swap them while you're in there. New hoses prevent leaks and improve long-term reliability.

What if my current radiator was leaking — how do I know if this one won't do the same?

This is a new core, not a rebuild. Internal corrosion from old coolant or a manufacturing defect caused your original leak. Use fresh coolant suited to your vehicle and flush the entire cooling system before installing this radiator to prevent repeat failure.
